When I try to log out of the GNOME I get no box appearing with logout/halt/reboot options. So I have to select Ctrl Alt Backspace and log back in and then it lets me. Also, when I fire up Linux in the morning it takes an excruciatingly long time for the GNOME to appear once I've typed my login and password.
Closing as it's for 6.0, no reports for recent versions
